4.1x00a0;Plastic materials, when used as transparencies, covers, or enclosures, are subject to wiping, cleaning, or other types of rubbing actions that cause abrasion. It is the intent of this test method to provide a means of estimating the resistance of such materials to this type and degree of abrasion. 1.1x00a0;This test method determines the resistance of transparent plastics and transparent coatings utilized in windows or viewing ports, to surface abrasion using oscillating sand. 1.2x00a0;The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1x00a0;Exceptionx2014;The inch-pound units in parentheses are provided for information only. 1.3x00a0;This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.4x00a0;This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
This standard specifies the list of test fluids to be used to demonstrate that components and subassemblies will not be adversely affected by contamination by fluids types that they may typically be exposed to. The fluids listed are representative of those commonly used and encountered in airborne and ground operations, and align with the requirements of fluids susceptibility of ISO 7137. This shall not be considered an exhaustive list and additional test fluids may be instructed in the product standard, against which compliance needs to be demonstrated. This standard, when used in conjunction with the test requirements defined in Clause 6 or the product standard shall be considered the starting point to test a component to determine its minimum performance capability when exposed to the fluids listed. Test results obtained from a number of sources over a considerable period of time have shown that, in many cases, widely varying results can be obtained when using fluids that are used in service. The practice of specifying fluids based on performance criteria rather than their constituents can mean variations in test results between batches of the fluid obtained from different manufacturers, or even from the same manufacturer. For this reason the EN 3909 Standard recommends the use of \"standard test fluids\" which are specified by their constituents and contain the chemicals that may be found in commonly used fluids. Where equipment may be exposed to fluid types that are not covered by Table 1 or where specific test fluids are considered to be necessary, the product standard shall identify the particular fluid required. If a manufacturer chooses to include additional test fluids (e. g. to satisfy a customer requirement), they do so at their own risk.
This European Standard describes laboratory methods for the identification of road marking materials used in horizontal signalization.
DIN EN ISO 105-B10 specifies a procedure for exposing textiles to artificial weathering in xenon-arc apparatus, including the action of liquid water and water vapour, in order to determine the weather resistance of the colour of textiles.
This document specifies laboratory methods for the identification of road marking materials used in horizontalsignalization. It is not necessary, unless required, to perform all of the tests described.
